In polytropic process (PVn = constant), if n = 1; it means a/an ______________ process?
Correct answer: B. Isothermal
- A. Adiabatic
- B. Isothermal
- C. Reversible
- D. None of these
Explanation
For an ideal gas, PV = nRT, so PV remaining constant means the temperature is constant. Thus, n = 1 in the polytropic relation represents an isothermal process, not necessarily an adiabatic or reversible one.
